a claims. (or. 295-46) The present invention has for its principal objects 10 to simplify and strengthen such constructions and to facilitate the mounting and removal of, the

bearings. Other objects and advantages will ap-.

pear hereinafter. The invention consists principally in the pro- 15 vision of separate bearing box members mounted on the ends of the axle housing. The invention I further in the roller bearing axle construction and in the parts and combinations and arrangements of parts hereinafter described and claimed In the accom yin drawings, wherein like reference characters refer to like parts wherever they occur,

The construction shown in the drawings is a locomotive drive axle.

Each end of the axle housing is provided with an outwardly extending radial flange or rib 8 from whicha tubular portion I with a cylindrical periphery extends outwardly. The ends of the axle housing body project as sleeve portions 8 into the chambers formed by said outer cylindrical portions 1. Mounted on each outer cylindrical portion I of the axle I is a bearing box 8 having 6 a cylindrical bore that may be lightly pressed on said cylindrical seat portion I. Each bearing box 9 has a radially extending flange or end wall portion III that is disposed adjacent to the rib ii formed by the portion of said housing rib that 10 projects beyond said seat I. A washer I2'and semi-circular shims l3 may be interposed between the end wall IU of the bearing box 9 and the housing rib Ii, the position of the box on said housing obviously being determined by the number and thickness of said shims. The hearing box 9 is secured to the housing 3 by means of screws ll extending through said housing rib into threaded holes in the end wall Io of the bearing box 9. The external configuration of the bearingbox is of the proper shape tocooperate with any desired type of frame 5.

Seatedineaehbearingbox9againstanouter annular end wall I! that is integral with'said box is the cup It or outer bearing member of a taper roller bearing, the cone II or inner bearing member being mounted on the axle l and tapered bearing rollers It being interposed between said "bearing members, preferably with a suitable cage "for said rollers. The bearings are disposed with the large ends of the rollers inwardly, that is, the bearing mounting is of the direct type. Interposed between the inner bearing cones I! is a spacersleeve 20 that has rings 2i secured to its ends and abutting against said bearing cones I1. Intheboreoftheouterendwall iiofthe bearingbox 9 isaclosureringfl thatcooperates with a ring mounted on the axle between the wheel hub and the adjacent bearing cone I'I.

Withthebodyofthe housing linposition,

the bearing cones I'I are secured upon the axle as desired, usually with a press lit with their ends against the ends of the spacer sleeve 2|, the cages II and bearing rollers I I being mounted on said bearlngcones II. The bearing boxes 5 9 are then placed on the cylindrical seat portions I of the axle housing 3, the requisite number of shims II n to give proper running clearance for the bearings inserted and the hearing boxes pressed home and secured in place by so the screws ll.

If it becomes necessary to strip the axle from the bearings, the bearing boxes 9 may be loosened by removing the screws II and the shims it, then the body of the axle housing I is mounted as in the yoke 24 of a press and the ram 25 of the is, each bearing is arranged with the smaller ends oi its rollers l8a disposed inwardly. In this modified construction, the axle housing 3a has a cylindrical end portion la and an outwardly projecting annular rib or flange I la at the innermost endof said cylindrical portion. A ring 30 is mounted on said cylindrical seat la, the outside diameter of said ring 30 being the same as that of the bearing cup l6a. A washer IZa is interposed between the innermost end of said ring 30 and the outer face of said housing rib Ila and shims i3a are interposed between said washer and the face of the endflange Illa of the bearing box So, thereby properly positioning the bearing box.

The axle housingis provided near each end with an inwardly extending radial flange 3| that overlaps the abutment ring Ila at the end of the spacer sleeve 20a, so that in stripping the axle, one of said flanges engages the adjacent abut- I ment ring to assist in the stripping operation.

The construction shown in Figs. 7, 8 and 9 is similar to that shown in Buckwalter Patent No. 1,967,806 dated -July 24, 1934, so far as concerns the external configuration of the bearing boxes 92;, and the bearing construction and arrangement. The bearings are of the double row direct mounted type, the outer bearing cups lBb being provided with a reinforcing ring 46 of the type shown in Buckwalter Patent No. 1,967,807. The bearing boxes 9b are provided with openings 4| in their sides through which project. the flattened side portions 42 of the bearing cups Nib. Bearing plates 43 are welded to said housing and cooperating bearing plates 44 are secured in the pedestal portions 45 o! the truck side frame 5b. l The constructions above described have important, practical advantages. They eliminate the necessity of longitudinal splitting of the axle housing, they strengthen the end portions oi. the housing where great stresses occur, they locate the securing screws at a point where they are relieved of end thrust and where they are easily accessible, they eliminate the necessity for separate closure rings at the outer ends of the housing and they facilitate the operation of mounting the bearings and stripping the axle from the bearings.

As appears from the drawings, the invention readily lends itself to the mou'ntingoi bearings of difl'erent types in journal boxes of various constructions. Obviously, the modifications hereinbeiore shown and described are only typical of the numerous modifications to'which my inventionlends itself, and I do not wish to be limited to the details of. construction hereinbefore set forth.
